Etymology

The noun is derived from Middle English mercurie (“metallic chemical element, quicksilver; a plant, probably goosefoot (genus Chenopodium); (possibly) dog’s mercury (Mercurialis perennis); etc.”), borrowed from Late Latin mercurius (“metallic chemical element, quicksilver”), Latin Mercurius (“Mercury, the Roman god of commerce, communication, etc.; the planet Mercury; etc.”), possibly from merc-, a stem of merx (“goods, wares; merchandise”); further etymology uncertain, possibly: * from Etruscan; or * from Proto-Indo-European *merǵ- (“to divide”), or *merkʷ- (“to grasp; to take”). The suffix -urius is also thought to be from Etruscan. Noun sense 1.1 (“metallic chemical element”) is from the association in medieval alchemy of the seven known metals—gold, silver, quicksilver, copper, iron, tin, and lead—with the Sun, the Moon, and the planets Mercury, Venus, Mars, Jupiter, and Saturn. An analogy was probably also drawn between the element being liquid at room temperature, and the Roman god Mercury’s attribute of swiftness. Noun sense 2 (“senses relating to plants”) is derived from mercurial (“(obsolete) any of the plants now known as mercury”, noun), from Middle English mercurial (“a plant, probably goosefoot (genus Chenopodium); (possibly) dog’s mercury (Mercurialis perennis)”, noun) from Anglo-Norman mercurial, Old French mercurial, or directly from their etymon Latin mercuriālis (“a plant, probably annual mercury (Mercurialis annua)”), short for herba mercuriālis (“(probably) annual mercury”, literally “herb or plant of the god Mercury”). Mercuriālis (“pertaining to the Roman god Mercury”, adjective) is derived from Mercurius (“the Roman god Mercury”) (see above) + -ālis (suffix forming adjectives of relationship from nouns). Noun sense 2.2.2.1 (“Blitum bonus-henricus”) is from the fact that this plant was often confused with annual mercury (noun sense 2.1). The verb is derived from the noun.
